FIXTURE HANGER.

Application filed August 18, 1925.` Serial No. 51,056.

My inventionv relates to fixture hangers and particularly to a noveltype of fixture hanger which is adapted to support electric lightfixtures.

t is 'the' object of my invention to provide a hanger which may besuitablymounted in the ceilingof a display room and in which an electriclight fixture may be supported.

In such a fixture hanger, it is my object to provide parts which will,with the hanging of an electric fixture, provide electrical contact witha source of current so that the lights in the fixture may be lighted byoperating a switch in the hanger.

The construction which it is my object to provide is particularlyadapted for use in display rooms and it furnishes a means of lightingthe fixtures independently so that each may be displayed by itself, andeach be lighted with a minimum wastage of electrical power.

It will further be found that where al display room is equipped withhangers made in accordance with my invention the installation of newfixtures and the interchanging of fixtures with relation to each otherwill be greatly facilitated.

Referring to the drawing in which I'have illustrated a preferredconstruction:

Figure 1 is a perspective view of a hanger hook.

Figure 2 is a side elevation of the hook without the connecting wires.

Figure 3 is a section along the line 3, 3 in Figure 2.

Figure 4 is a longitudinal vertical section of my preferred type ofinsulation bar.

Figure 5 is a perspective view of the hanger assembly.

Generally indicated at 1 is the hook member to which a fixturefmafy besecured. The hook has a lower shank portion 2 which preferably is bothinternally and externally' threaded so that more than one type offixture may be supported in the hook member without the necessity ofusing additional bushings and couplings for each different type offixture. The hook member has a hook portion 3 with fiat sides on whichare disposed strips of insulation 4 and contact plates Screws 6 may beutilized to retain the insulating and contact plates on the sides of thehook portion. All screws in the hook member are insulated from eachother, (as indicated at 7) so that they will not short circuit in thehook member. Electric wires vthe ring wit-h screws, projecting through 8are connectedto the conta-ct plates as shown vby the heads 9 of thescrews.

Fixtures of any desired types which are not illustrated as they form nopart of my ,60 invention, may be suitably assembled on the hook membersprior to hanging. The convenience of being able to connect the xtureswith contact plates which connect with an outlet box forming part of thesupporting structure will bel apparent when it is considered that theold wa'y Ofhanging fixtures required the connecting of the wires fromthe lights in the fixtures with sources of current in the ceiling whilethe person connecting the fixture was standing on a ladder. With my typeof hook no ladders are required excepting in so far as the hanger may besufficiently high up to require a ladder to elevate the fixture to aproperly suspended position.

The construction of the parts which make up the supporting structurecomprises a member which may be attached in the ceiling, and a rigidmember on which spring clips in a circuit are mounted, vwhich issufficiently strong to support a desired fixture.

` In the illustration l have shown the ceiling engaging member in theform of a ring 10 with a fianged lower portion 11 in which a hole 12provides space for inserting the hook member. The ring is provided witha cross member 13 suitably mounted in the sides of holes in the ring,and is provided with one round hole 14 in the center of the cross memberand an oblong hole 14a on each side of the round hole. The round hole inthis member is adapted to be used when the hanger is installed whereattachment is made to an outlet box already in the ceiling or wall, andthe oblong holes are adapted to be used with screws when the hanger isattached to the ceiling or wall. VExtending' across the ring is a rod 15of insulating material which may ne suitably mounted in the sides of thering with screws, projecting through the holes in the ring. The rod hasdisposed on its outer surface a pair of conductive spring clips 16 whichare secured to the rod and extend toward opposite sides of the rod andthe clips have their adjacent ends 17 bent over and sufficientlyinterspaced from each other so that the Contact plates on the hookmember will engage theends and establish electric contact with theclips. One of the clips is connected with the negative, neutral orground lead line of an electric circuit as indicated and the other isconnected With a switch 18 which is provided in the hanger. 'lhe switchmay be suitably secured to the sides of the ring, and as Will be readilyunderstood, the switch is connected With a positive or live lead line byWhich current may be supplied to the fixture.

Modifications otl structure ivill readilyoccur to those skilled in theart Without departing from the principle ofl my invention hereindisclosed.

Having thus described my invention, what l claim as new and desire tosecure by Letters Patent, is: y

l. A fixture hanger comprising in combination with a mounting; memberhaving a rod vof insulating material mounted on the member, springcontacts disposed on the rod, the spring contacts connected with asource of current, and a fixture engaging member with insulated hookshaped conductive plates thereon adapted t0 be connected with lights inthe iixture, and the engaging member adapted to hook on the rod With theconductive plates in contact with the spring contacts.

2. A separable outlet for electric fixtures embodying a hooked fixtureengaging member with conductive plates on the outer sides of the memberadapted to be connected With lights in a fixture, a supporting memberadapted to be retained on a Wall, interspaced spring contacts and arodof insulationniaterial in the supporting member Vsupporting the springcontacts, and the plates adapted to engage the contacts with the hookmember suspended from the rod.
